"Counting Rabbits" joke
One day, during math class, the teacher asked Little Johnny, "If I give you two rabbits, two rabbits and another two rabbits, how many would you have?"
"Seven," replied Johnny.
"No, Johnny. Listen carefully this time. If I give you two rabbits, two rabbits and another two rabbits, how many would you have?" asked the teacher.
"Seven!" insisted Johnny.
"Let's try this another way. If I give you two apples, two apples and another two apples, how many would you have?" the teacher asked.
"Six," Johnny answered.
"Good, Johnny, that's right," said the teacher. "Now, if I give you two rabbits, two rabbits and another two rabbits, how many would you have?"
"Seven!" Johnny said.
"Johnny, how on earth do you work out that three lots of two rabbits would be seven?" asked the baffled teacher.
"Easy. I already have one rabbit at home now!" Johnny replied.
